ISLAMABAD - Level of concern has risen sharply in the country, as during the last few months as many as 2,936 cases have been diagnosed dengue positive with 21 reported deaths. According to the statistics, blood samples of as many as 5,399 suspected dengue fever patients have been received, out of which 2,936 cases were diagnosed positive. In Islamabad, 137 out of 433 suspected dengue fever cases were announced positive, whereas two deaths have been confirmed. This year, Sindh has remained the most affected province where a sharp increase has been witnessed in positive cases and so far, 1,688 dengue positive cases have been reported with 16 deaths across the province. Punjab is next after Sindh as the number of positive cases has reached 975 with two deaths. Likewise, the total suspected cases registered in Khyber Pakhtunkwa are 317 of which 131 are laboratory conformed. The confirmed cases in Azad Jammu & Kashmir are 55 with 5 patients testing positive and one death. Interestingly Balouchistan is the only province where not a single case has been reported and the situation is quite positive over there. The large number of dengue patients tested positive speaks volumes of the efficiency and competency of the health authorities concerned to deal with the deadly disease. Despite the governments tall claims of controlling dengue fever, the numbers of dengue victims are increasing as compared to the previous years. Every time when the disease turns into an epidemic, the health authorities remain confined to make just special arrangements. The deadly viral disease dengue fever regularly occurs almost every year but still the authorities have failed to come up with a comprehensive preventive plan to tackle the fatal disease. According to health experts the dengue fever is caused by the bite of a female mosquito. The mosquito transmits the disease by biting a person after biting an infected person. Dengue virus having no proper cure, can only be avoided by adopting precautionary measures. Most dengue infections result in relatively mild illness, but some can progress to dengue hemorrhage fever. With dengue hemorrhage fever, the blood vessels start to leak and cause bleeding from the nose, mouth, and gums. Bruising can be a sign of bleeding inside the body. The time between the bite of a mosquito carrying dengue virus and the start of symptoms averages 4 to 6 days, with a range of 3 to 14 days. An infected person cannot spread the infection to other persons but can be a source of dengue virus for mosquitoes for about 6 days, however the mosquito that causes the disease dies as the winter approaches.
